Procedure

A suitable reactor is charged with acetone (38 mL). The acetone solution is sequentially charged with carvedilol (11.08 grams) and water (8 mL). Upon addition of the water, the slurry dissolves completely with heating. To the solution, 1N Mandelic acid in methanol (1 Equiv. 27.3 mL.) is added. The resulting mixture is stirred at the range between 17° C. and 35° C., and the solid precipitate is formed over 10 hours to 24 hours. Later, the mixture filtered and the cake is washed with a mixture of acetone and water (10 to 1) at 3 volumes or 33 mL. The cake is then dried under vacuum to a constant weight. The final weight is 8.34 g, 54.5% yield.
